Luke Norris struck 20 minutes from time to hand gutsy Dagenham a 1-1 draw against promotion-chasing Southend.
An end-to-end clash saw the Shrimpers extend their unbeaten run to eight games.
And the honours were even during what was an entertaining, yet goalless first half. Southend started well, with both Will Atkinson and Kevan Hurst forcing fine saves out of home goalkeeper Chris Lewington.
At the other end Dan Bentley was equally athletic in keeping out efforts from Dagenham striker Rhys Murphy.
On the stroke of half-time Dagenham's Zavon Hines saw a well-struck shot superbly beaten away by Bentley before the visitors went in front eight minutes after the restart.
Atkinson neatly teed up Hurst, and his miscued shot just beat the unlucky Lewington.
Two minutes later it was almost 2-0 as Anthony Straker drilled inches wide.
Dagenham evened it up midway through the second half, when Gavin Hoyte crossed in low for Norris who smashed high into the net.
Murphy came close to nicking a Dagenham winner late on, but a draw was a fair result.
